Refs #6086 Added Warnings and more results
Refs #6840  Conditionally set lattice errors

The lattice parameters could be created by constrained optimization or
other not constrained least squares techniques. Currently, only lattice
parameters created via unconstrained least squares are used.

Ideally, constraints will be for conventional cells only, so this method would
not be used except for niggly cells whose orientation matrix is optimized by
unconstrained least squares.
